The Bussmann series HHG fuse holder is an in-line fuse holder for ATC blade fuses. Versions are available without covers or with covers for splash protection. Also available with easyID LED blown fuse indicator. ATC blade fuses are used to protect a car's electrical system including the vehicle's lights, engine, air conditioner, heat, wipers, and more. They are the standard for most modern automobiles, vans and light trucks. All of our fuses are color coded and have the amp rating stamped on the front to make them easy to identify. The transparent housing also lets you see when the fuse is blown, allowing you to quickly identify which fuse needs to be replaced. Bussmann easyID fuses and holders are the easiest option when it comes time to replace a fuse in your vehicle. Figuring out which fuse needs to be replaced is not fun for anyone but easyID fuses make it simple. Instead of testing each fuse with a fuse tester, trying to figure out the fuse panel diagram, or pulling out each fuse one-by-one, Bussmann's easyID fuse technology lights up an LED bulb to let you immediately know which fuse is blown.
